Watch Scrapheap Challenge online: Episode 3 Sharp Shooters

The challenge This week’s Scrapheap Challenge is a test to see who can build the most extreme rapid-fire arrow launcher. The teams will have to build a projectile launcher that can automatically load itself, as well as quickly firing arrows far and accurately. Stage Crew The boys from behind the scenes! Our Bristolian bodgers Pup, Denzel and Jet are responsible for contraptions used in shows such as Jesus Christ Superstar, Mary Poppins and Miss Saigon. Passionate, animated and enthusiastic is the only way to describe them. Captain Pup’s eyes light up when he talks engineering and he is supported by the bearded Denzel with his hearty laugh and Jet, so-called because of his love for jet engines. This team is used to the pressure of having to perform and with their ‘The show must go on’ attitude, is unlikely to disappoint. The Stage Crew’s expert is a friend of the show, Tod Todeschini. Tod began life as a kitchen product designer but he soon got bored. He is now a medieval weaponry expert and maker of special effects for stage and television. This is his third outing to Scrapheap Challenge and having previously tackled Giant Darts and Rapid Fire, this week's test should be a cinch! The Big Dippers The Big Dippers are Lancashire lads responsible for the maintenance of Blackpool Pleasure Beach. Dodgey (he loves car boot sales and ferreting in skips – should be at home on the heap then!), Steve and Brian (nicknamed Two-ey as he only has two front teeth) have been friends for years and have a wealth of experience. Dodgey comes from a family of mechanics, Steve is the electrics supervisor at the Pleasure Beach and Brian claims to be able to weld underwater. So as well as providing a constant level of cheeky banter, these guys are here for more than the ride! In The Big Dippers’ corner is expert armourer John Nixon. John spent 10 years learning his trade as an armourer with REME (Royal Electrical and Mechanical Engineers), before splitting his time between armoury and mechanics. Nowadays, he is most likely to be found on a film set making guns for epics such as Black Hawk Down and Saving Private Ryan. Let’s see if he will save the day for The Big Dippers! The judge Our judge this week is another Scrapheap veteran, Steve Ralphs. Grand Master of the Traditional Bowyers Guild, Steve began crafting traditional bows and arrows 25 years ago. He now spends most of his time instructing Hollywood actors in the art of archery (this is the man that taught Legolas how to draw a bow). When he’s not doing that he plays guitar in a band called Phabulous Fondue!
